12.3.3.3 Configuration tips
Configure the ACL based flexible QinQ on MAN access layer switch's two
interfaces (G0/1 and G0/2 of Switch A) connecting with the corridor
convergence switches, so as to distinguish user traffic and meet the application
requirements.
Generally, PPPOE dialing is used in broadband Internet service, with protocol
number being 0x8863/0x8864 typically; IPoE is used in IPTV service, with
protocol number being 0x0800 typically.
